Electric guitar string sets .015: ultimate power and tone for the most serious guitarists
Do you want absolute control, a deep tone, and strings that won't weaken under any circumstances? Then .015 electric guitar string sets are exactly what you're looking for. These extremely heavy strings are designed for guitarists with experience, power, and a clear preference for a rich, stable, and powerful sound. Ideal for jazz, slide, stoner rock, and extremely low tunings.
What are .015 electric guitar strings?
A .015 string set starts with a 0.015-inch first string—the thickest gauge in standard electric guitar strings. A typical setup is:
.015 – .018 – .028 – .040 – .052 – .065 , although variations may occur depending on brand or application.
Thanks to their enormous string tension, .015 strings offer unprecedented levels of tone control, projection, and stability. These sets are especially suitable for experienced guitarists with a heavy playing style, or for those working in very low tunings.
Benefits of Electric Guitar String Sets .015
1. Massive, deep tone with rich harmonies
Due to their thickness, .015 strings produce an exceptionally full tone—from thundering bass to warm midrange. Perfect for those who want every note to shine.
2. Very suitable for extremely low tunings
Do you tune your guitar to C, B, or lower? .015 electric guitar strings will maintain a tight, clear sound without compromising tone or intonation.
3. Exceptional tuning stability and reliability
Even with aggressive playing, slide techniques or heavy downpicking, these strings remain stable in tune and free from fret buzz.
4. Full tone control for expressive playing
The high tension gives you complete control over tone, sustain, and vibrato. Ideal for styles where expression and dynamics are essential.
Important considerations with .015 strings
.015 string sets aren't suitable for everyone. Their heavy tension can be tiring during long playing sessions or fast solos. Switching to this string gauge almost always requires a complete setup of your guitar (truss rod, intonation, string height).
These strings perform best on hollow body guitars , baritones , or heavily built solid bodies that can handle the extra tensile force.
Are you using them for slide or open tunings? Then .015 strings offer the ideal combination of resistance and pitch stability.
Brands such as Thomastik-Infeld , D'Addario , Ernie Ball , and GHS offer top-quality .015 sets for professional use.
